For example, my main audio track fades in from silent to -28db and stays that way for about twenty seconds. Then it transitions to 0db and remains that way for the rest of the track. Everything works fine with it until I do a "Render Preview". Then the audio track plays at a sound level of 0db the whole way through, even though the keyframes with the initial values still exist. This pretty much drowns out the dialogue track. Unfortunately, this also carries over when rendering the project.
Also, is there a simple way to remove the render preview?
